A sediment content associated to a solubility fraction of sediment Fe is added to the freshwater fluxes of iceberg and ice shelf. For ice shelf, the parameterization of Mathiot et al. (2017) is used for the distribution of Fe throughout the water column. For iceberg, a homogeneous distribution until 120 m of depth is applied. modified routines : - p4zsbc.F90 - p4zsed.F90 Intermediate variables to compute ziron variable in p4zsed:\\ - zironberg : "iron from iceberg freshwater flux"\\ - zironisf : "iron from ice shelf freshwater flux" In namelist_pisces, 3 parameters are added:\\ - isffeinput : "Fraction of bioavailable iron from ice shelves"\\ - icbfeinput : "Fraction of bioavailable iron from icebergs"\\ - icbdep : "Mean underwater depth of iceberg (level depth)" === Documentation updates {{{#!box width=55em help Using previous parts, define the main changes to be done in the NEMO literature (manuals, guide, web pages, …). }}} ''...'' == Preview {{{#!box width=50em info [[Include(wiki:Developers/DevProcess#preview_)]] }}} ''...'' == Tests {{{#!box width=50em info [[Include(wiki:Developers/DevProcess#tests)]] }}} ''...'' == Review {{{#!box width=50em info [[Include(wiki:Developers/DevProcess#review)]] }}} ''...''
